摘　　要：采用粉末冶金法制备了多壁碳纳米管/氧化铝混杂增强铝基复合材料,并测试了其密度和硬度,初步分析了其组成物相,测定了室温下与振幅有关的阻尼。结果表明,多壁碳纳米管/氧化铝混杂增强复合材料的密度有所减小,硬度明显提高;室温下,低振幅阻尼较小,高振幅阻尼较大。Aluminum composites with multi-walled carbon nanotubes（MWCNT） and alumina are prepared by powder metallurgy method. The density and hardness of composites are measured. The phases of structure are detected. And the damping related the amplitudes are surveyed. The results show that the densities decrease, hardness increases, and the damping related with smaller amplitudes in room temperature is lower, the damping related with larger ones at same temperature is higher.
